User reviews are generally not a good place to look for help in the computer arena. Most issues are a PICNIC; Problem In Chair, Not In Computer. Me and my friends all use Linksys routers and they work fine. I avoid D-Link like the plague as nothing I have ever used from them has worked well. I figure that is basically blind luck as others have the opposite experience. It sounds like you are looking for a simple solution. Considering these things are pretty cheap I suggest getting the cheapest one you can and try it out. If it does not serve the purpose then toss it and get something else to fix the problem or add needed functionality.

I suggest you look at the Apple Airport base station. The USB connector could be a great value add for a shared printer or backup drive.
